• Alarm management standard update

    ANSI/ISA-18.2-2009, Management of Alarm Systems for the Process Industries, has found wide use across the process industry sectors. The standard addresses the development, design, installation, and management of alarm systems in the process industries. Alarm system management includes multiple work processes throughout the alarm system lifecycle. The standard defines the terminology and models to develop an alarm system, and the work processes recommended to effectively maintain the alarm system throughout the lifecycle.

    An International Electrotechnical Commission (IEC) version of the standard, IEC 62682, was published in late 2014. ISA18 co-chairs Donald Dunn and Nick Sands led the IEC work as convenor and secretary/editor, respectively. IEC 62682 eliminated country-centric criteria that were present in the original standard.  In addition, there was a shift of the normative criteria (should to shall) within IEC 62682. The IEC work used a single editor (Sands) in lieu of clause editors as had been used in writing the original ISA-18.2, promoting a more cohesive document with consistent wording and terminology throughout.  

    In leading the IEC work, the ISA18 co-chairs elected to edit the ISA-18.2 standard by incorporating the changes implemented during the IEC work and then submitting the document to ISA18 for comments. For this reason, ISA18 is now well positioned to complete a revision of ANSI/ISA-18.2.  A committee ballot on the revision was issued in mid-May, and will be completed in time for results and comments to be reviewed at the next face-face ISA18 meeting on June 15-16, 2015 in Raleigh, North Carolina, in conjunction with the ISA Leaders Meeting.

    Also meeting at that time will be ISA18 Working Group 1, which will be reviewing input received in a recent review of ISA–dTR18.2.01, Alarm Philosophy. This technical report (TR) supports ISA-18.2 by providing guidance on how to implement the recommendations and requirements described in the alarm philosophy clause of the standard.  It outlines potential approaches and provides specific examples that can be included in an alarm philosophy in order to properly manage the identification, rationalization, detailed design, implementation, operations, maintenance, monitoring/assessment, management of change, and audit lifecycle steps.
